Fear not, anon! God does not call everyone to marriage and/or sex, and that’s beautiful – we are all called down diverse paths and to use our unique gifts. It could be that you are called to the single life, or else to marriage without sex – both are perfectly possible for a faithful Christian, and biblically/traditionally based.
There is a rich history of asexuality in Christianity, one that reaches all the way back to Paul himself (or even to Jesus, if you want to interpret his single life as the possibility of him being ace/aro). Check out 1 Corinthians 7, where Paul advocates for the single life, saying that “I wish all people were like me” (i.e., not interested in sex/marriage).
Some people also interpret Matthew 19:12, where Jesus talks about how some people are born eunuchs (people who could not procreate) or made eunuchs “for the sake of the kingdom of Heaven”, as being about asexuality. You can definitely read that passage as evidence that Jesus was totally cool about people who don’t have sex/reproduce!
Post-Biblical times, you can read about Christians like St. Cecilia and her husband (from the early 3rd century) who entered into celibate marriages, or like Santa Rosa de Lima (from the early 1600s) who shunned marriage in favor of a celibate single life. So as you can see, sex and procreation are not imperative to being a faithful Christian!
It’s funny how mainstream Christian thought shifts over time. Back in the first several centuries of Christianity, for example, celibacy was actually the way to be! It was exalted over sex, and the single life was exalted over marriage. These days, for Protestants especially, the balance has shifted in the other direction – marriage is “better” than the single life, and (procreative, marital) sex is “better” than celibacy/abstinence.
I am of the firm opinion that exalting either abstinence over sex or sex over abstinence is simply absurd. To each person are given different gifts, and a different vocation. If God does not call someone to a life that includes sex but they feel pressured by other Christians to have sex (with a spouse, most likely) anyway, I think that’s so sad and often yields bad fruit.
We can best glorify God by doing as God wills for us as individuals – not what God wills for some other people, you know? And I think that being asexual, or being sex repulsed, or simply not feeling any desire for sex are all possible signs that sex is not a part of your calling. Maybe marriage is, and maybe it’s not – just keep reflecting and discerning what God’s call for you actually is, not what other people claim it is.
A note on reproduction in particular: some people these days interpret God’s command to the first humans to “be fruitful and multiply” as evidence that God wants everyone to have kids (and thus, of course, everyone must have sex). That’s just…not a reasonable conclusion. Moreover, there are plenty of people who are having kids – humanity as a whole is doing the whole “multiplying” thing just fine without every single person reproducing. (Also, if one day you feel called to raise children, well, there are plenty of ways to do that without having sex! There are so many children in need of adoption right now.) And there are more ways to “be fruitful” than having children – good fruit comes in many forms.
To close this: I myself am asexual and my girlfriend and I plan to get married someday! I never get any pressure from her to have sex now or in the future – so I promise, it is possible to find someone who will love and respect you as you are, if you do feel called to that kind of relationship.
You are fine and even precious in God’s eyes as you are – so don’t pay any mind to the people who claim you “have” to have sex or have children to be faithful. You don’t. You can be most faithful by discerning God’s will for you and doing your best to glorify God as you are.
